srurrme on untrue FOR BOXES Ann THE LIKE.

Application filed July 14,1919. Seriall No. 310,621.

To all whom it may concern:

Be it known that I, OSCAR H. F RITSCHLE, a citizen of 'the United States, residin at the borough of Manhattan, city of ew York, county of New York, and State of NewYork, have invented a certain new and useful Improv ment in Stufling or Fillingfor Boxes an the like, of which the following is a specification.

'Myinven tion relates to improvements in articles of manufacture intended for use, as a protecting stufier or filler for boxes of various sorts holding articles that are apt to be easily crushed or injured by jarring, scratching or otherwise. My invention also is'adapted to be used-as a matting, as a surgical dressing, and for many other purposes.

My invention relates more particularly to articles -of manufacture, as above described, composed of a number of layers of cellulose stiffened.

An object of my invention is the production of articles of manufacture of the chais acter above described, having great resiliency and springiness.

A further object of my invention is the roduction of said articl s of manufacture iiavin'g moisture insulating qualities.

Other objects aresimplicity, inexpensiveness and facility of manufacture.

Still other objects and advantages of my will appear from the following description.

I shall now describe the embodiment ,of my invention illustrated in theaccompany; ing drawing, and shall thereafter "point out my-invention in claims. Figure 1 is a plan 'view of a sheet of stufling or filling embodying my invention.

Figure 2 is an edge view thereof.'

Figure 3 is a cross-section taken on the line 3-3 of Figure 1.

Figure 4 is an enlarged edge view of a single cellulose sheet.

.Figure 5 is a side elevation of rollers used in the manufacture of my invention.

Figure 6' ,is an end elevation thereof.

In the illustrated embodiment of my invention, the article of manufacture is shown as a flat body 1 havin suitable ornamental depressions 2 thereon or the purposes here- I ject-ions 7 1n the roller 5.

inafter set forth. v

sheets suitably reinforced and.

shown in Figures 5 and 6, a

The body 1 consists of a number of la ers of cellulose sheets 3 and a layer of suitable heavy paper or other backing 4. The .cellulose sheets 3 are very thin and highly porous. When a number of these sheets are superimposed, a relatively large quantity of air is enclosed and caughtin the unitary structure making it highly-resilient but at the same time very flexible and limp.-. This enclosed or entrapped air adds. to the natural resilience of the cellulose sheets making the complete structure very springy' and resilient. For many purposes the limpness in the body 1 is objectionable andthis is overcome by making-suitable depressions 2 in the superimposed cellulose sheets These depressions may preferably be of an" ornamental character ,so as to be pleas ing to the eye.' sions 2, the layers together at the points of the depressions 2, thus forming. relatively stiff portions in the body 1. In making the depressions, care should be taken that they are so arranged as not to detract too much from the resiliency and springiness of the article. This is accomplished by proper spacing of the depressions. The layer 4 may be of any suitable paper preferably having a glazed surface. I have found in many instances that it is'preferableto use" a waxed or pare afiined paper or a paper commonly knownin the .trade as glassene. This paper acts as a moisture insulation either keeping out moisture or retaining .it. The article of manufacture thus in addition to acting in a stufling or filling capacity tends to proteot the commodity wltli which it is used In making these depresoriginal condition. It is especially usefulin packing candy.

In manufacturing my invention, the cellulose sheets3 are usuall laid upon each other until the desired thickness is reached and if desired a small amount of adhesive may be used between the sheets. Thesev cellulose sheets are then joined to the layer 4 by running them through any suitable rollers 5-and 6, such for example as are suitable adhesive being used, between the sheets 3 and the layerx4i The depressions in. the sheets 3 may be formed by havin proper proe roller 6 is 3 are very tightly" pressed from the atmosphere andkeeps it in its 3 usually plain. The rollers 5 and 6 are spaced a suitable distance from each other. In running the sheets 3 and backing layer t through the rollers, the sheets 3 are next to the roller 5 and the backing layer A is next to the roller 6., The Projections 7 press certain portions of the sheets tightly against the backing layer A and form the depressions '2. After being run through the rollers, the body 1 is then cut to any desired size and is ready for use.

It is obvious that various modifications may be made in the construction shown in the drawing and above particularly described Within the principle and scope of my invention.

1 claim:

1. Abox filling consisting of a number of superimposed cellulose sheets and a back ing layer of glassene.

2. Abox filling consisting of a number of superimposed cellulose sheets and a backing layer of Waterproof material 3. A box filling consisting of a number neiaeee of superimposed cellulose sheets and a backing layer of oiled paper,

4, A box filling consisting of a number of superimposed cellulose sheets, a backing layer therefor, and depressions formed in the cellulose sheets adapted to stifi'en and hold the sheets together. I

5. A box filling consisting of a number of en erimposed cellulose sheets, a backing there or, and depressions in the cellulose sheets adapted to stiffen and hold the sheets together, the portions surrounding the depressions being soft and resilient.

6. A filling for candy boxes, consisting of a number of superimposed cellulose sheets, each sheet composed o1 a single layer of cellulose'fibers, a backing layer therefor,

and depressions formed in the cellulosev sheets adapted to stiffen and hold the sheets together.

In testimony whereof l have signed my nam to this specification this 7th day of July, 1919.
